|
## Overview
|
|
|
|
*NextHooker* is an open-source x32~~/x64~~ text hooker for Windows.
|
|
|
|
Basically, GUI text hooker based on [Stomp](http://www.hongfire.com/forum/showthread.php/438331-ITHVNR-ITH-with-the-VNR-engine)'s ITHVNR.
|
|
|
|
## Extensions
|
|
|
|
See my [Example Extension project](https://github.com/Artikash/ExampleExtension) to see how to build an extension.
|
|
|
|
To use an extension, simply rename the extension dll file to ```{NUMBER}_nextvnr_extension.dll``` and copy into the NextVNR folder.
|
|
|
|
Extensions are called in order by the number they are prefixed with.

## Compiling
|
|
|
|
Before compiling *NextHooker*, You should get CMake, [Windows Driver Kit 7.1](http://www.microsoft.com/en-us/download/details.aspx?id=11800), and Visual Studio.
|
|
|
|
## Project Architecture
|
|
|
|
The GUI links to vnrhost.dll (created from the texthook folder) which injects vnrhook.dll (created from the vnrhook folder) into the target process and connects to it via 2 pipe files.<br>
|
|
vnrhost writes to hostPipe, vnrhook writes to hookPipe (duh?)<br>
|
|
vnrhook waits for the pipe to be connected, then injects a few instructions into any text outputting functions (e.g. TextOut, GetGlyphOutline) that cause their input to be sent through the pipe.<br>
|
|
Additional information about hooks is shared through a section object that is mapped to a reference to the Hook class.<br>
|
|
The text that vnrhost receives through the pipe is then processed a little before being dispatched back to the GUI and displayed.
